BURNER.

SPECIFICATION forming part of Letters Patent No. 743,148, dated November3,1903.

Application filed May 2, 1903. Serial No. 155,295. (No model.)

ing at Pittsburg, in the county of Allegheny and State of Pennsylvania,have invented certain new and useful Improvements in Burners, of whichthe following is a specification,

reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inlamp-burners, and relates more particularly to that class of burners inwhich a wick is used and wherein a burner is suitably connected to thetop of the lamp in which the oil is contained.

The object of the invention is to provide a burner whereby a light maybe quickly and readily'oxtinguished when desired.

A further object of this invention is to provide a burner which isabsolutely non-explosive, thereby overcoming the dangers which have beencoincident with the use of a lamp of this type.

In describing the invention in detail reference is had to theaccompanying drawings, forminga part of this specificatiomand whereinlike numerals of reference indicate like parts throughout both views, inwhich- Figure 1 is a side elevation of a lamp equipped with my burner,the same being partly in section. Fig. 2 is an elevation looking towardthe right of Fig. 1, the same being in section.

The reference-numeral 1 indicates a screwthreaded portion of the burner,which is connected to the metal part 2, fused onto the lamp-bowl 3.Secured to the upper edge of the part 1 is a shell 4, on the upper endof which the brackets 5 5 are secured, these brackets extendingoutwardly and support ing at a point intermediate of their length thelamp-strainer 6, upon which the cap 7 is pivoted. Extending through part1 in either direction is a wick-casing 8, the lower end of which extendsnearly to the bottom of the lamp-bowl and is provided with apertures 9for the purpose of admitting the oil to the wick contained therein, andthe upper portion of this wick-casing extends nearly to the top of thecap 7 and has provided and secured to its outer edges the slottedmembers 9 9. Pivotally mounted on the wick-casing inside the casing 4 isa lever 10 for actuating the extinguisher of the lamp, said leverpreferablyextending outwardly and slightly below the wheel 11, by whichthe vertical position of the wick is controlled. The said lever 10 has ashort arm 12, the end of which is provided with a slightly-enlargedportion 14, which engages in the member 15, which is suitably formed tohave the enlarged portion 14 operate therein. Attached to the upper sideof this member 15 is a vertical rod 16, which passes through the bracket17, formed on the side of the wick-casing S, and a coilspring 18encircles said rod 16 between member 15 and bracket 17 for the purposeof keeping the rod 16 in its lowered position. The upper end of this rod16 has a loop formed thereon which engages the lower edge of theextinguishing-cap 19, said cap having projections 20 20 on either sidewhich extend through the slots in the members 9 9.

The operation of this part of the burner is as follows: When it isdesired to extinguish the. light, the lever 10 is depressed, therebyelevating the extension 12 thereof, the enlarged portion 14 of whichwill elevate member 15, carrying with it the rod 16, thereby compressingspring 18, and the extinguishingcap may be moved upward until such timeas extensions 20 reach the ends of the slots in the members 9, when thecap 19 will be forced over the top of the wick-casing 8,thereby snuffingthe wick and efiectually extinguishing the light. The screw-threadedpart 1 is provided with a plurality of apertures 21, which permit thegas which may be formed within the bowl of the lamp to pass upwardly andinto the casing 4, and a plurality of apertures 22, provided in thelower portion of said casing, to permit the same to escape to theoutside air, thereby preventing the accumulation of gas within the bowlof the lamp.

Another feature of this invention consists in having wick-casing 8 ofsuch length between its connection with the bowl of the lamp and theigniting-point of the wick that at its point of entrance into thelamp-bowl the same will be cool, thereby also doing away with the dangerwhich now results from the parts which are in contact with the oilbecoming heated.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, 18-

1. In a lamp-burner, the combination of a wick-casing, to the centralportion of which a member adapted to connect the burner with the bowl ofthe lamp is secured, and a portion of said casing extending within saidlamp, the lower end of the same being provided with oil-inlet apertures,the upper end of which wickcasing being provided on its edges withslotted guides in which projections formed on the snuffer plate extend,said plate having a rod pivotally connected to its lower end, the lowerend of said rod being pivotally connected with an actuating-leverwhereby said plate may be thrown into operative position, and a springnormally holding said plate in its inoperative position, substantiallyas described.

- 2. In a lamp-burner, the combination of a wick-casing, a member forconnecting the same with the body of the lamp having apertures thereinfor the escape of gas from the bowl of the lamp, the lower end of saidcasing extending Within the oil and being provided with a plurality ofapertures, a snufier-plate located adjacent to the upper end of saidcasing and having a limited sliding connection therewith, a rodpivotally connected to said plate, means for elevating said rod wherebysaid plate may be brought into operative position, a spring normallyholding said plate in its inoperative position, whereby the gas mayescape from the bowl of said lamp, substantially as described.

3. In combination with a lamp of the character described, a wick-casinghaving a lower portion adapted to extend within the oil and providedwith a plurality of apertures, slotted members carried by the upperportion of said wick-casing, a snuffer-plate slidably engaging with saidslotted members and means for actuating said snu l ter-plate,substantially as described.

4. In a lamp of the character described the combination with the bod yof the wick-casing, means for connecting said casing with the body, saidcasing being provided with a lower extended portion projecting throughsaid connecting means within the oil of the body and being provided withoil-inlet apertures, slotted members secured to the upper portion ofsaid wick-casing, a snuifer-plate slidably secured to said members,means for actuating said snufEer-plate, and means for normally holdingthe plate in inoperative position.

5. In a lamp of the character described a wick-casing, means forconnecting the same with said lamp having apertures therein for theescape of gas from the lamp-bowl, said casing having anoutwardly-extended portion provided with a plurality of aperturesadapted to admit oil to the wick, slotted members secured to the upperportion of said wick-casing, a snuifer-plate having slidable connectionswith the slots of said members and means for actuating saidsnufier-plate, substantially as described.

In testimony whereof I aflix my signature in the presence of twowitnesses.
